Since Beaz has negative value, the Suns would be wise to insist he be included in a Gortat trade. The Green, Bass, Melo for Gortat, Beaz and filler trade works because it gets the Suns out from under Beaz's money, gives them a project center with a ton of upside, and gives them two solid rotation players right now at a reasonable cost.
I have a feeling that the Suns would want a first round pick in the deal. Maybe Ainge can get a 2nd rounder back.
I'm not afraid of the Beaz on this team, although I've been a long time non-fan. He's the cost of doing business when you're trying to get an affordable center and don't want to give up young rotation players. Doc and Boston is as good a place as any to see if his talent can be harnessed.
